Does the institution use timers to regulate temperatures based on occupancy hours in at least one building?:
Yes

A brief description of the technology used:

Approximately 75% of Arizona State University's buildings at the Tempe campus can be scheduled through the building automation system. This is a Johnson Controls Metasys system that is used to turn air handlers and pumps, etc. on and off according to the scheduling needs for a particular building, or zone within a building. Building occupancy needs are determined by academic, research, and administrative staff, then equipment schedules are optimized to prevent unnecessary run-time.

The Polytechnic campus employs a system called Direct Digital Control (DDC). It’s an allergen system that controls and maintains temperature ranges between 68-80 degrees. It also generates reports on use of energy, remote monitoring and alarms.

West campus buildings have been upgraded to Computerized Direct Digital Controls. Buildings are operated based on the needs of the customer reducing building systems operating hours by over 50%.
